English Abstract At the National Institute of Public Health and
Environmental Protection a workshop was held on bioavailability of
continaminants for micro- organisms in relation to biological treatment of
hazardous waste. At the moment the application and development of
biological treatment techniques is hampered by residual concentrations
exceeding the standards set by the government. Research in this field is
stimulated within the framework of different R&D programmes. This workshop
was organised to discuss the desired research strategy in this field for the
Innovation-oriented Research Programme on Environmental Biotechnology. On
this workshop it was concluded that the development of biological treatment
techniques for heavy metal containing hazardous waste does not seem very
promising. Other (physical-chemical) treatment techniques will probably be
more effective. the biological removal of organic pollutants seems much
more promising.
